About Matthieu

17 years of experience at the intersection of software development and tech team transformation.

Backend developer (Java/Kotlin, Spring Boot) with a focus on building the right products with the best possible practices.
Also 8 years spent coaching teams and organizations — at Air Liquide, Fortuneo, Orange — on their delivery.

This dual background allows me to work on both technical topics and team organization: understanding issues in depth, removing obstacles, improving how we work together.

Attentive to industry evolution and new practices, I regularly stay updated on what's transforming software development. In this regard, I am particularly interested in what AI is concretely changing in teams — tooling, organization, new ways of collaborating and delivering.

Independent since 2017. Based in Rennes, hybrid missions.
